Shrub rose plant named ‘BAIpome’

ABSTRACT

A new and distinct variety of landscape shrub rose plant is provided which abundantly forms on a continuous basis single cup-shaped light soft pink blossoms having a white center. The plant exhibits a compact, tight, and rounded growth habit, glossy medium green foliage, and excellent tolerance to Black Spot and Powdery Mildew. The attractive medium green glossy foliage contrasts nicely with the light blossom coloration. A tough rose plant of small stature and good hardiness is provided. The plant can be grown to advantage as a specimen, border planting, or as a mass planting.

Botanical designation: Rosa hybrida.

Varietal denomination: ‘BAIpome’.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida landscape shrub rose plant was createdat Yamhill, Oreg. during 1995 by artificial pollination wherein twoparents were crossed which previously had been studied in the hope thatthey would contribute the desired characteristics. The female parent(i.e., the seed parent) was the ‘Noatraum’ variety U.S. Plant Pat. No.7,282). The male parent (i.e., the pollen parent) also was the‘Noatraum’ variety. The parentage of the new variety can be summarizedas follows:‘Noatraum’×‘Noatraum’.

The seeds resulting from the above pollination were sown and plants wereobtained which were physically and biologically different from eachother. Selective study resulted in the identification during 1998 of asingle plant of the new variety having the distinctive ornamentalcharacteristics hereafter described.

It was found that the new variety of the present invention:

-   -   (a) exhibits a compact, tight, and rounded growth habit,    -   (b) abundantly forms on a continuous basis in clusters        attractive single cup-shaped light soft pink blossoms having a        white center,    -   (c) forms glossy medium green adult foliage,    -   (d) displays excellent tolerance to Black Spot and Powdery        Mildew; and    -   (e) is particularly well suited for growing as attractive        ornamentation in parks and gardens.

The young rose pink flower buds open to the light pink blossoms having awhite center that cover the bush throughout the season. The aging petalscommonly detach cleanly and do not detract from the attractiveness ofthe blooms. A tough shrub rose plant having good hardiness is provided.

The new variety is a small stature versatile landscape plant that wellmeets the needs of the horticultural industry. It can be grown toadvantage anywhere in the landscape where attractive ornamentation isdesired. The distinctive blossoms are displayed throughout the season.The plant can be grown as a specimen, border planting, or as a massground cover.

The new variety can be readily distinguished from other varietiesincluding its parental ‘Noatraum’ variety. More specifically, the‘Noatraum’ variety forms much darker pink blossoms with near whitecenters.

The new variety has been found to undergo asexual propagation by buddingon an understock and by the rooting of cuttings. ‘Dr. Huey’ rootstock(non-patented in the United States) was used during the budding. Suchasexual propagation by these techniques at Yamhill, Oreg., St. Paul,Minn., and at Phoenix, Ariz. has shown that the characteristics of thenew variety are stable and are strictly transmissible by such asexualpropagation from one generation to another. The new variety grows wellon its own roots.

Initially the new plant was designated ‘95K61-1P’. The new varietysubsequently has been named the ‘BAIpome’ variety, and currently isbeing marketed while using the PINK GNOME and GARDEN PATH trademarks.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show as nearly true as it is reasonablypossible to make the same in a color illustrations of this character,typical specimens of the new variety. The rose plants of the new varietyhad been propagated by the rooting of cuttings, were approximately twoand three years of age, and were being grown outdoors at St. Paul, Minn.and at Yamhill, Oreg.

FIG. 1 illustrates typical plants with blossoms in various stages ofopening and foliage of the new variety. Clusters of the attractivesingle cup-shaped soft pink blossoms with white centers are shown.

FIG. 2 illustrates a close view of typical buds and fully open flowersof the new variety in greater detail.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart). Common color terms are tobe accorded their ordinary dictionary significance. The description isbased on the observation of two and three year-old plants while grownoutdoors on their own roots during June and July 2002 and 2003 at St.Paul, Minn., and July 2003 at Yamhill, Oreg.
